Machine integrated positioning system

ABSTRACT

A machine integrated positioning system shows an operator where to place a raw part in the press brake or other machinery. Further, the operator is informed if the dimensions associated with the raw part are, or are not, correct to produce the planned finished part. The operator is visually shown how the raw part is to be oriented. The operator is informed if the raw part is right-side-up, along with other pre-final placement information. If these and other conditions are not met, the machine integrated positioning system may prevent the press brake and other machinery from cycling.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation of U.S. patent application Ser. No.16/539,276, filed on Aug. 13, 2019, which claims the benefit of U.S.Provisional Application No. 62/718,101, filed on Aug. 13, 2018. Theentire disclosure of the above application is hereby incorporated hereinby reference.

FIELD

The present disclosure relates to parts forming machines and, moreparticularly, a system and method for ensuring placement of a raw partin a machine to correctly form a finished part.

BACKGROUND

The use of lasers in the machining industry is generally known. Inparticular, modern equipment with manufacturing parts will often employlasers and associated sensors for safety reasons. For example, lasersensors may be used to determine if a person inadvertently moves to ahigh risk or dangerous area relative to the manufacturing equipment bycrossing a light beam. In such situations, the equipment may beautomatically stopped to ensure the safety of the person adjacent theequipment.

Conventional laser-vision positioning systems have also been employed todirect an operator where to place a raw part in a machine. However,these conventional laser positioning-vision systems do not, in advance,show an operator how to orient the raw part or inform the operatorwhether the raw part is upside down or backwards when installed into apart forming machine for manufacture of a finished part. This isespecially a problem for non-symmetrical parts. Further, the knownpositioning systems do not, in advance of final placement in themachine, determine if the raw part is the correct part for a plannedforming operation.

There is a need to integrate either laser or vision positioning systemswith machinery, such as a press brake, so that these added concerns areaddressed prior to final placement of the raw part in the machinery.Desirably, these systems would militate against a cycling of the pressbrake and other machinery if the above-noted conditions are not met.

SUMMARY

In concordance with the instant disclosure, a machine integratedpositioning system, which operates in advance of placement or forming ofa raw part or “blank” in a press brake and other machinery, issurprisingly discovered.

In one embodiment, a machine integrated positioning system includes aparts forming machine, a vision device, and a controller. The partsforming machine is configured to receive a raw part with a register markfrom a raw parts station disposed adjacent to the parts forming machineinto an initial forming position. The parts forming machine is alsoconfigured to, through an operation, form the raw part into a finishedpart for subsequent delivery to a finished parts station disposedadjacent to the parts forming machine. The vision device is disposedadjacent to the parts forming machine and configured to detect analignment of the register mark of the raw part. The alignment of the rawpart indicates at least one of a correct location and a correctorientation. The controller is in communication with the vision device.The controller and configured to permit the operation of the machine toform the raw part into the finished part where the register mark of theraw part is aligned, and to not permit the operation of the machine toform the raw part into the finished part where the register mark of theraw part is not aligned.

In a further embodiment, a machine integrated positioning systemincludes a parts forming machine, a light positioning device, a visiondevice, and a controller. The parts forming machine is configured toreceive a raw part with a register mark from a raw parts stationdisposed adjacent to the parts forming machine into an initial formingposition. By operation, the parts forming machine is also configured toform the raw part into a finished part for subsequent delivery to afinished parts station disposed adjacent to the parts forming machine.The light positioning device is affixed to the parts forming machine.The light positioning device is configured to project a light beam to atleast one of the raw parts station, the initial forming position, andthe finished parts station. The vision device is affixed to the partsforming machine. The vision device is configured to detect an alignmentof the register mark of the raw part with the light beam projected bythe laser device, and thereby an orientation of the raw part. Thecontroller is in communication with the light positioning device and thevision device. The controller is configured to permit the operation ofthe machine to form the raw part into the finished part where theregister mark of the raw part is aligned with the light beam, and to notpermit the operation of the machine to form the raw part into thefinished part where the register mark of the raw part is not alignedwith the light beam.

For example, the controller could send a pass/fail signal, so that themachine is the one with the logic to control the machine advancement ornot. In the case of a manual operation, the laser could tell theoperator where to position and machine (e.g., weld) a part, then thevision system could tell the operator if it is correct or not. So, inthis case the controller is not necessarily integrated into the machine,and can provide a passive or reactive feedback loop with a digitaldisplay. Alternatively, the controller could be integrated and not allowthe machine to operate (e.g., strike an arc) if it detects an issue.

In another embodiment, the light positioning device is configured toproject the light beam to each of the raw parts station, the initialforming position, and the finished parts station. The light positioningdevice may further be configured to project the light beam to anadvanced placement position for the raw part. The advanced placementposition is spaced apart from and disposed adjacent to the initialforming position for the raw part. The vision system may include camerafor capturing an image of the register marks and the light beams forprocessing by the controller.

In a further embodiment, the light positioning device is movablyattached to the parts forming machine. For example, the lightpositioning device may be disposed adjacent a top of the parts formingmachine and is movable laterally toward each of the raw parts stationand the finished parts station. The light positioning device may furtherbe configured to move from a rearward position to a forward position.The rearward position is arranged above the advanced placement positionfor the raw part. The forward position is arranged above the initialforming position for the raw part.

In yet another embodiment, the parts forming machine includes a pressbrake. A press brake is a machine pressing tool for bending sheet andplate material, most commonly sheet metal. It forms predetermined bendsby clamping the workpiece between a matching punch and die. Typically,two C-frames form the sides of the press brake, connected to a table atthe bottom and on a movable beam at the top. The bottom tool is mountedon the table, with the top tool mounted on the upper beam. While themachine integrated positioning system may be especially advantageouswith respect to press brake equipment, it also should be understood thatthe machine integrated positioning system may be used with other typesof machines, and particularly other types of parts forming machines,within the scope of the present disclosure.

It should be appreciated that this system has the ability to work inconjunction with about any type of manufacturing operation, e.g.,machining, stamping, turning, manual and robotic welding. The strengthof the system lies with human interference. There are also otherapplications with programming the equipment and helping to visually seeif there are problems with programs. The system would also help bycreating points automatic programming to display the next point to moveto in an operation.

In yet a further embodiment, a machining method may include a step ofproviding the machine integrated positioning system of the presentdisclosure. The method may include the further steps of moving the rawpart to the initial forming position, and projecting, by the lightpositioning device, the light beam to the initial forming position. Anorientation of the raw part may then be manually adjusted in order toalign the register mark of the raw part with the light beam. Analignment of the register mark of the raw part with the light beam inthe initial forming position is then detected, by the vision system. Thealignment indicates the orientation of the raw part at the initialforming position is correct. The operation of the parts forming machineto form the raw part into the finished part is then permitted, by thecontroller in response to the alignment indicating the orientation ofthe raw part is correct. This check of the orientation of the raw partupon being inserted into the initial forming position can be helpful inminimizing scrap associated with mis-oriented raw parts. The operatormay subsequently move the finished part from the parts forming machineto the finished parts station.

In an additional embodiment, the machining method may further include astep of projecting, by the light positioning device, a light beam to theraw parts station. This informs the operator where the raw part is to beefficiently and safely stored prior to the moving of the raw part fromthe raw parts station to the initial forming position. The positioningof the raw parts station may be predetermined based on efficiency inmovement of the operator and safety considerations associated with theparticular type of parts forming machine being employed. Likewise, themethod may include a step of projecting, by the light positioningdevice, a light beam to the finished parts station. This informs theoperator where the finished part is to be efficiently and safely storedupon the moving of the finished part from the parts forming machine tothe finished parts station. As with the location of the raw partsstation, the location of the finished parts station may be selected toensure optimum efficiency and safety in the manufacturing process.

In particular embodiment, the manufacturing method may further include astep of moving the raw part from the raw parts station to an advancedplacement position. This step will occur prior to the step of moving theraw part to the initial forming position. In this example, the methodmay also include steps of providing the light positioning device in arearward position arranged above the advanced placement position, andthen projecting, by the light positioning device, a light beam to theadvanced placement position while in the reward position. An alignmentof the register mark of the raw part with the light beam projected tothe advanced placement position is then detected by the vision system.The alignment indicates the orientation of the raw part at the advancedplacement position is correct. This pre-check of the orientation of theraw part prior to being inserted into the initial forming position canbe helpful in minimizing scrap associated with mis-oriented raw parts.Following this pre-check, between the step of detecting, by the visionsystem, an alignment of the register mark with the light beam projectedto the advanced placement position and the step of moving the raw partto the initial forming position, the method may include a step of movingthe light positioning device from the rearward position to a forwardposition. In the forward position, the light positioning device maylikewise be employed to check for the proper orientation of the raw partupon being moved to the initial forming position.

It should be appreciated that the manufacturing method furtheradvantageously includes a step of not permitting, by the controller, theoperation of the parts forming machine to form the raw part into thefinished part when the alignment of the register mark of the raw partwith the light beam in the initial forming position is not detected bythe vision system. This automated prevention of a cycling of the partsforming machine until the correct orientation of the raw part has beenconfirmed further minimizes the manufacturing of defective finishedparts and the accompanying scarp associated therewith. In anotherexample, it should be understood that control for the cycling may begiven to the operator, who will receive feedback on the alignment of theraw part via a display or other means such as a red light or green lightto indicate correctness of location and/or orientation.

In yet another embodiment, the manufacturing method may include a stepof projecting, by the light positioning system, a shaped imageassociated with a profile shape of the raw part to the initial formingposition. This informs the operator if the dimensions associated withthe raw part are correct or not. For example, if the raw part has adefect in shape or form, or is even an incorrect raw part for theapplication, it will not be circumscribed by the shaped image projectedinto the initial forming position.

In yet an additional embodiment, the manufacturing method may include astep of generating on a display in communication with the controller anidentifier to confirm for the operator at least one of whether theorientation of the raw part at the initial forming position is correct,and whether the dimensions associated with the part are correct.

In still another embodiment, the manufacturing method may include a stepof projecting, by the light positioning device, written instructionsonto one of a floor adjacent to the parts forming machine and a surfaceof the parts forming machine. The written instructions may inform theoperator on proper operation of the parts forming machine, for example.The written instructions may also include warnings relating to safety oractions that must be taken in order to proceed in the manufacturingmethod. A skilled artisan may select suitable written instructions to beprojected by the light positioning device, as desired.

In still a further embodiment, the manufacturing method may include astep of projecting, by the light positioning device, a profile oroutline of at least one human hand onto a surface of at least one of theraw part and the parts forming machine. The at least one profile of ahuman hand informs the operator on a location for safe placement of thehands of the operator during the operation of the parts forming machine.

In an exemplary embodiment, the machine integrated positioning systemprovides a combination of at least one of a laser positioning system anda vision system. Thereby, in advance of initiating a forming operationon a raw part in a press brake or other machinery, an operator caninitiate a machine part program along with a laser-vision system thatshows the operator where to place and orient raw parts in the machinery.This results in preventing the parts from being formed if the raw partis not properly placed in the machine.

Further, the operator may be informed if the dimensions associated withthe raw part are or are not correct to produce the planned finishedpart. The operator may be visually shown how the raw part is to beoriented, to avoid allowing the raw part to be placed upside down orbackwards. This is especially true for non-symmetrical parts in pressbrakes, where it is very easy to otherwise load the non-symmetrical partin upside down or backwards and by doing so the part is formedincorrectly. The operator may also be informed if the raw part has thecorrect orientation, e.g., is right-side-up. As a result, mistakes andscrap parts are avoided and correct final parts are ensured.

The vision system could measure the part and ensure it is correct aswell. The laser system could show the profile view of the final partafter manufacturing and operators could visually see what is wrong byholding the part in the correct location. The vision system couldfurther auto adjust the machine so the next part will be producedcorrectly.

The feedback and controls of the machine integrated positioning systemallow for projection onto a floor therearound the machine so that largeraw parts, unique featured raw parts, and two-man operators can bebetter controlled than current systems. Also, the added controlsprovided by the positioning system informs an operator when to grab apart to avoid pinched fingers. The system may also facilitate a loadingand an unloading of parts, stack locations for the raw parts to befinished, provide special notes to the operator by projections, such astooling notes, locations, correct tooling, and the like. The system mayalso direct the operator by projections where to stand and hold theparts.

This machine integrated positioning system, however, is not limited toonly the above-stated pre-final placement conditions. If any one ofthese pre-final conditions is not met, the machine integratedpositioning system may prevent the press brake and other machinery fromcycling.

In a particular embodiment, the system incorporates into a parts-makingprogram, for a press brake or other machinery, added examination of araw part that utilizes laser positioning to visually show an operatorwhere to place the raw part. This added examination is done in advanceof final placement of the raw part in a press brake or other machinery.The advance parts-making programming includes, for example, theprojection of laser lines to accomplish at least one of thefollowing: 1) where to place the raw part, 2) if its position iscorrect, 3) if the raw part is upside-down or right-side-up, 4) if itsorientation is correct, and 5) if general dimensions of the raw part arecorrect for forming a desired output part. The programming may bedevised in order to optimize an efficiency of part production. Thesystem may also include the projection of laser to form words or amessage, and even outlines of hands to indicate proper placement.

These various functions are accomplished before final placement of theraw part in its proper position for forming. Subsequently, theexamination can then be interfaced with existing vision systems, whichdo not incorporate such advanced part-making programming, or permitmanual cross checks by an operator. Thereby, press brakes and othermachinery are prevented from cycling if the raw part has not been fullyexamined or is improperly oriented prior to a cycling of the machinery.Thus, final parts are better formed to avoid excess scrap and damage tothe machinery.

DETAILED DESCRIPTION

The following description is merely exemplary in nature and is notintended to limit the present disclosure, application, or uses.Throughout the drawings, corresponding reference numerals indicate likeor corresponding parts and features. In respect of the methodsdisclosed, the order of the steps presented is exemplary in nature, andthus, is not necessary or critical unless otherwise disclosed.

As seen in FIG. 1 , there is illustrated a prior art machine or system 1that merely directs an operator (not shown) on where a raw part 2 is tobe placed in an initial forming position 3, within a CNC press brake 4(see arrow pointing therein). The press brake 4 has a ram 5 with anupper die 6 and a lower die 7. The system 1 may incorporate a laserdevice or a vision device 8, for example, that projects a beam 8 a toinform the operator on where to generally place the raw part 2 in theinitial forming position 3 and possible subsequent forming positions.For example, the operator may align an edge of the raw part 2 with theprojected beam 8 a in order to ensure the raw part 2 has been pushedinto the press brake 4 to a proper location for forming. Also shown is astart-stop control box 9 that the operator uses to control the ram 5. Asestablished hereinabove, the system 1 of the prior art is prone tohaving the operator load the raw part 2 into the press brake 4 in anincorrect orientation, regardless of whether the raw part 2 is in thecorrect position. The system 1 of the prior art also does notcontemplate directing the operator to stations for incoming raw parts oroutgoing finished parts for optimized efficiency in production of thefinished parts.

A machine integrated positioning system 10 according to variousembodiments of the present disclosure is illustrated in FIGS. 2-5 . Thepositioning system 10 works in conjunction with a press brake 12 orother machinery (not shown). Although the press brake 12 is shown anddescribed herein, for purpose of illustrating the machine integratedpositioning system 10 of the present disclosure, it should beappreciated that the machine integrated positioning system 10 may beused with other suitable types of machinery and equipment, as desired.The terms “form” or “forming” as used herein is also defined to includeany operation used for manufacturing the finished part 22 from the rawpart 20, and can include operations such as bending, stamping, molding,cutting, welding, removing material, adding material, and the like, asnon-limiting examples.

As shown in FIG. 2 , the press brake 12 has a ram 14 which has an upperdie 16 and a lower die 18. To form a raw part 20 into a finished part22, an operator or an automated system like a robot (not shown) movesthe raw part 20 from a raw parts station 24 thereof to an initialforming position 28, and then subsequently to an outgoing or finishedparts station 40 containing the finished parts 22. It should beappreciated that the raw part 20 in FIG. 2 spans the bottom die 18 wherein the initial forming position 28. In an optional embodiment, the rawpart 20 may be moved to an advanced placement position 26, which is inadvance (i.e., prior) to the initial forming position 28. The raw partsstation 24 is shown to the left of the press brake 12. The advancedplacement position 26 is represented by a stand, which could take otherforms.

It should be appreciated that the advanced placement position 26 may notbe necessary in certain embodiments, depending on part shape andgeometry, as all the necessary checks can be caused to happen at theinitial forming position 28. Often, in the forming operation, there willalso be a back gage (not shown) to push the raw part 20 against, butoperators may still mis-position the raw part 20. So, the initialforming position 28 becomes crucial. Furthermore, some raw parts 20 arehard to position because of their geometry, so the positioner will allowthem to more precisely position parts to make more consistent andtighter tolerance parts.

The positioning system 10 further comprises at least one lightpositioning device 42 and a vision device 44 that operate in unison.Although the light and vision devices 42, 44 are shown in FIGS. 2 and 4being movably affixed to the press brake 12, it should be appreciatedthat these components may be provided on a separate structure, such as astand or frame, that is spaced apart from the press brake 12. The lightpositioning device 42 is configured to create a light beam and thevision device 44 is configured to detect light and images. Althoughlaser beams are described as a specific type of the light beam herein,it should be understood that other types of light sources are consideredto be within the scope of the disclosure. It should be appreciated thatthe light positioning device 42 and the vision device 44 may be providedseparately and be spaced apart from one another, or may be providedtogether as single unitary component of the system 10, as desired. Asshown in FIG. 2 , the light and vision devices 42, 44 are typicallyplaced above the initial forming position 28 for interaction with theraw parts 20 and finished parts 22, as shown by four dashed lines 46,48, 50, 52.

The light positioning device 42 of the present disclosure may include alaser projector that is configured to generate and emit at least onelight beam. The laser projector may be configured to project changinglight beams to at least one of the initial forming position 26, theadvanced placement position 26, the raw parts station 24, the finishedparts station 40, the floor adjacent to the press brake 12, and one ormore surfaces of the press brake 12 itself. The light beams may create astationary or moving point, image, letters and numbers, or words asdescribed further herein. The laser projector may include a housing thatcontains lasers, actuators or motors connected to movable mirrors tosteer the light beams, galvanometer scanners, and other opticalcomponents. The laser projector can contain one laser light source forsingle-color projection or three sources for RGB (red, green, and blue)full color projection. One of ordinary skill in the art may also selectother suitable types of components and systems for the light positioningdevice 42, as desired.

In certain example, it should be appreciated that the vision device 44may be employed without the light positioning device 42, for example, bycapturing images using ambient light available. However, it should beappreciated that the use of the light positioning device 42 does presentcertain advantages, including providing the operator with an easy visualon the positioning and orientation of the raw and finished parts 20, 22throughout the operation.

The vision device 44 of the present disclosure may include a digitalcamera with an optical system such as a lens with a variable diaphragmand shutter to focus light onto an image pickup device having at leastone image sensor. The diaphragm and shutter admit the correct amount oflight to the image sensor. The digital camera can include at least oneof a wide-angle lens and a telephoto lens to take images of both thearea of the system 10 as a whole and also of a focused area of just theraw part 20. The digital camera can display images on a display 30immediately after being recorded, for example, and store and deleteimages from memory. A skilled artisan may also select other suitabletypes of components and systems for the vision device 44 within thescope of the present disclosure.

It should be appreciated that the vision device 44 may further beemployed to also record work, mistakes, time, and efficiencies. Thisinformation could work in conjunction with an ERP or MRP system orsimilar systems to record work and production rates and used for problemsolving issues talking to other team members at another facility.Advantageously, such recording could also be used for training, and inthe case as machines become more automated, could help trainingprogrammers on how to better program.

As represented by a first double arrowed line 54, which is shown abovethe press brake 12 in FIG. 2 , the light and vision devices 42, 44 canbe moved from a position within the top of the press brake 12 to aposition just outside of the front top of the press brake 12. Forexample, the light and vision devices 42, 44 may be connected to arotating drum that can be rotated by an actuator or motor to move thelight and vision devices 42, 44 from a rearward position (disposed abovethe advanced placement position 26) to a forward position (disposedabove the initial forming position 28). This can be done automaticallyby the controller 60, or manually by the operator, with the one or moreof the light and vision devices 42, 44 placed high enough to see it all.By moving the light and vision devices 42 to the rearward position justoutside of the front of the press 12, the light and vision devices 42,44 are then capable of viewing and sensing various features associatedwith individual raw parts 20, finished parts 22, and stacks 24, 40 ofthe parts 20, 22 of all sizes, shapes, and placements.

Examples of features of the parts 20, 22 and stacks 24, 40 to be used inat least one of positioning and orienting the parts 20, 22 throughoutthe manufacturing process are register marks 56. The register marks 56may be defined by holes, indentations, internal profiles or shapes,reflective material, lettering, barcodes, and safety notes, asnon-limiting examples. For orientation purposes, it may be particularlyuseful to have more than one register mark 56, although a single one ofthe register marks 56 is shown in FIGS. 2-5 for simplicity ofillustration. The register marks 56 relate to a variety of partcharacteristics, for example, dimensions, thickness, quantity of parts20, 22 in the stacks 24, 40, part surface characteristics, orientation,placement, and upside and downside characteristics, to name just a few.In particular, where the raw part 20 is not symmetrical, the registermark 56 may be offset from a lateral centerline of the raw part 2 sothat a location of the register mark 56 may be used to confirm a correctorientation of the raw part 2 at various points throughout themanufacturing process. In another example, the register mark 56 could bethe overall shape or profile of the raw part 2 such that a non-alignmentof the overall shape or profile can be indicative of at least one of thelocation and the orientation of the raw part 2 being incorrect andrequiring intervention by the operator prior to the forming process. Oneskilled in the art may also select other suitable types, numbers,features, or locations for the register marks 56 within the scope of thepresent disclosure.

In a further example, the light positioning device 42 may be employed toproject an actual image of the raw part 2 to the initial formingposition 28. This may assist the operator in the locating andorientation of the raw part 2, such that the projected image effectivelyis superimposed over the raw part 2 and not otherwise noticeable wherein exact alignment with the raw part 2. This can be detected by thevision device 44, or simply may be provide a visual aid to the operatorto ensure proper placement, prior to the cycling of the machine.

As a further representation of movement of the light and vision devices42, 44, a second double arrow headed line 38 is shown horizontally tothe right outside top front of the press brake 12 in FIG. 2 . Thisindicates that the light and vision devices 42, 44 can be laterallymoved to various positions to the sides of the initial forming position28, for example, along a channel or rail of the machine 12 by operationof an actuator or motor, but preferably across the outside top of thepress brake 12. In these outside positions, the light and vision devices42, 44 are then capable of monitoring and detecting the above-statedfeatures and characteristics of the parts 20, 22 in the stacks 24, 40and in the advanced placement position 26 and the initial formingposition 28. These capabilities have not been provided thus far in theart.

If the machine integrated positioning system 10 detects any defects orcautionary features and characteristics, such as a misalignment of oneof the register marks 56, the operator is informed by way of an alarm orwarning or a message 30 that may be provided on a mounted touch terminal32 or a separate terminal 36. The warning provides feedback to theoperator to stop the process and reassess the location or orientation ofthe raw part 20. The system 10 may not allow the press brake 12 toproceed in its forming operations, i.e., the system 10 prevents acycling of the press brake 12, until the defects are properly handled.

A controller 58 of the system may be provided with suitable software orlogic for operation of the system. In particular, the controller 58 mayinclude at least one processor and at least one memory. The memory maybe a computer readable medium having non-transitory processor-executableinstructions tangibly embodied thereon.

Advantageously, the present disclosure includes an integration of thecontrols for the light and vision devices 42, 44 with the machinecontrols when the part programs are pulled up on the terminals 32, 34,36. The terminals 32, 34, 36 may have a human interface such as a touchterminal 32 or keyboard 34, as shown in FIG. 3 . FIGS. 2 and 3 furtherillustrate the controller 58 that communicates with the mounted touchterminal 32 or the separate terminal 36 by way of a separate computer60, or that the computer 60 may be embedded in either the controller 58or the terminals 32, 36. The terminals 32, 36 may be integrated into themachine controllers, for example. The connections between the controller58 and the terminals 32, 36 can be by way of hard wiring 62 or a remotewireless connection 64, as desired.

In operation, if there are no defects or cautionary features and nonegative characteristics found by the system 10, associated with the rawparts 20, which would be detected by signals from the dashed lines 46,48, then the operator may cause the machine to operate and form thefinished part 22. Alternatively, the operator may move the raw part 20from the initial placement position 26 to the final placement position28. At this point, the light and vision devices 42, 44 are moved into aposition in view with the dashed line 50. In this position, the system10 will view and sense various features associated with the raw part 20as the upper die 16 moves vertically downward toward the lower die 18 tomake initial intimate contact with the raw part 20. This intimatecontact and possible additional contacts form a desired final form(s) ofthe finished part 22, wherein the operator might subsequently place thefinished part 22 on the stack 40 thereof, in preparation for ensuingoperations.

If, at any point within the above-stated process, the system 10 detectsa defect, then the process steps may be halted, and further cyclingstopped until corrections are made.

In a further example, shown in FIGS. 4 and 5 , the light positioningdevice 42 may be further employed to project written instructions ontoone of a floor adjacent to the parts forming machine 12 and a surface ofthe parts forming machine 12. The written instructions may inform theoperator on proper operation of the parts forming machine 12. The lightpositioning device 42 may also be used to project a profile or outlineof at least one human hand onto a surface of one of the raw part 20 andthe parts forming machine 12. The profile or outline informs theoperator on a location for safe placement of the hands of the operatorduring the operation of the parts forming machine 12. It should beappreciated that each of the projection of the written instructions andthe profile or outline of human hands for placement purposes may becontrolled by the controller 58 and may be predetermined by programmingor selection through the terminals 32, 34, 36 depending on the finishedpart 22 to be manufactured. This may further help in positioning toolingin the correct location and/or ensure the correct tooling is in theproper location, for example, the upper and lower punches and dies in apress brake machine.

Advantageously, the machine integrated positioning system 10 of thepresent disclosure operates in advance of forming of the finished part22 from the raw part 20 in the parts forming machine 12 such as thepress brake or other machinery, to minimize the manufacture of defectivefinished parts and scrap.

While certain representative embodiments and details have been shown forpurposes of illustrating the invention, it will be apparent to thoseskilled in the art that various changes may be made without departingfrom the scope of the disclosure, which is further described in thefollowing appended claims.

What is claimed is:
